LED Lights Offer Longer Life & Lower Operating Costs
LED lights are a wise option for savvy people looking for a long life, environmentally smart (no mercury), compact alternative to conventional lighting. LEDs come in an astounding variety of shapes, sizes, designs, colors and capacities for both the home and office.
LEDs generally have a high initial purchase cost, but this cost is more than offset by a lowered power bill over many years given the higher efficiency and longer operating life. The low operating heat level contributes to their long life. Some units are rated with an operating life of 50-70,000 hours.
In addition to home and office lighting, LED GU10 units can also be used in many different settings and including architectural and entertainment lighting, city street lighting, hospital lighting as well as portable lighting. On average, LED units operate at around 5 percent the power required to run a conventional 60 watt bulb.
Focusing on LED bulbs, they are 10 to 50 times more energy-efficient. They can decrease operating costs by up to 90%. They can be used in existing sockets. An LED bulb has a working life as much as 50 times longer, an operational life of a huge 50,000 hours, possibly longer. By comparison, incandescent last only a few thousand hours.
In technical terms, LEDs have high luminous efficacy; they deliver more lumens per watt than virtually all forms of conventional lighting. Indicatively, each watt of electrical power allows incandescent lights to deliver about 15 lumens, halogens 18 lumens, LEDs 70 lumens and fluorescents 90 lumens.
Similarly, LED downlights are also making strong inroads. They tend to be made with greater power capacity than bulbs. They are supplied at up to 10 watts per unit. Like bulbs, they are available in socket types, multiple colors and have a dimming capacity and can be installed on alternating (AC) or direct (DC) power systems.
In summary, LED lights represent the lighting of the future, now. They are an intelligent choice for many reasons. Even though they have less luminous efficacy than fluorescent tubes, fluorescents cannot be installed in as wide a range of settings.
